v 1 This invention relates and/or laundry tray unit or the like and particularly to a structure of this kind adapted tobe equipped with a removable drainboard.

An object of the invention is to provide a sink or tub unit having two spaced basins orsumps separated by a double wall partition with a. laterally extending rim extendingcontinuously around four sides of the sumpsand in whichthe walls of each sump are joined to therim by an ofiset portion forming a stepextending continuously around theunit and constructed to support a sliding drainboard, the improved construction being such that the drainboard may be positioned over either sump and when so positioned will slope toward the opposite or uncovered sump so as to drain water thereinto. a v

A further object. of the invention is to provide an improved double basin or sump unit capable of being used as a sink or laundry tub or a combination thereof, the. structure being pro.--. vided with an improved sliding drainboard sup: ported in improved manner and adapted to be positioned over either sump.

Another object of theinvention is to provide a slidingor removable drainboard for a doublebasin or sump unit which may be supported in inclined fashion over either sump by engagement of one. end with the double wall partition separating the sumps and of the opposite end with an offset step formed in the end wall of the sump, the construction being such that the drainboard may also be supported in any intermediate position.

Still a further object of the invention is to pro-.

vide an improved sliding drainboard whichmay be supported in inclined manner for draining purposes over either sump of a double sump sink or laundry tray unit. and without necessitating anyalteration in the construction of the unit to enable the drainboard to be positioned, and supported in this manner. f

Another object of the invention is toprovide a structure as above described in which the drain board may be positioned over either sump in such manner that it will slope or be inclined in one 5 Claim. (01. 4187) to a combination sink 2 l constructed in accordance with the present invention. a

Before explaining. in detail the present invention it is to be understood that the invention is not limited in its application to the details of con-- struction and arrangement of parts illustrated in the accompanying drawings, since the invention is.

capable of other embodiments and of being practiced or carried out in various ways. to be understood that the phraseology or terminology employedherein is for the purpose of description and not of limitation.

In the drawings there is illustrated, by way of example, one embodiment of the present invention as applied to a combination sink'or laundry tray unit preferably formed from sheet steel. The sink or laundry tub unit in its final form after fabrication is provided with two spaced sumps or basins I0 and. I I. i In the present instance these sumps are shown as having the same depth although it will be understood that one forming a step or ledge which; as illustrated in Fig. 1, extends continuously around the three sides of each of the sumps. The side walls of the sumps above the offset H terminate in a laterally extending generallyhorizontal flange or rim I 8 which may be pierced to provide apertures or holes I9 for the reception of :fastening devices by means of which the sink or laundry tray unit may be secured to a support in any conventional manner. i

The sumps or basins l0 and II are separated:

by means of a double wall partition 20. One Wall 20a of this partition forms an end wall of the sump l0 and the other wall 20b of this partition forms an end wall of the sump II. It will be Also it isa small distance above the bottom of the offset H, the latter at the ends of the partition will have offset portions Ila of somewhat less depth than the depth of the offset; i=1. shown in Fig. 2, the line 2| indicates substantially the bottom of the offset step 11 extend ing con tinuously around three sides of each sump and it will be seen that the curved top c of the double wall partition intersects this Each of the side flanges 24 is formed at opposite ends thereof with a notched or recessed portion 3i shaped to correspond substantially to the shape of the curved top 200 of the double wall partition 20. The notches or recesses are positioned equal distances from the end flanges so that when the drainboard is positioned over either sump, as in the manner shown in Fig. 2, one of the notches or recesses 3| will fit over and embrace the top of the partition when the opposite end flange 25 of the drainboard fits into the offset step 1.1 and is supported thereby. When the drainboard is thus positioned it will be supported at one end upon the step I? and at the opposite end on the upper edge 200 of the partition and will slope so as to drain water into the uncovered sump.

offset and at its highest point extends a small distance above the line 2| although below the plane of the marginal rim or flange [8. The top surface of the partition curves downwardly at opposite sides so as to merge smoothly into the adjoining step portions H.

The sink or laundry tray unit is provided with a sliding drainboard 22 which may be pressed or stamped from sheet metal. The top surface of the drainboard is formed with longi tudinal drain grooves 23 and the front and rear longitudinal sides of the drainboard are formed with downwardly extending parallel flanges Z4 terminating in inturned' flanges 24a. The ends of the drainboard are also bent down to provide depending end flanges 25 eachof which is preferably shaped, as shown in Fig. 2 to conform substantially to the shape of the offset step l1. Thus, "when the drainboard is positioned over the sump ID in the manner shown in Fig. 2, the shaped end flange 25 thereof will substantially fit into the offset step i? in the end wall [2 of the sump so as to be supported thereby. In like manner, when the drainboard is similarly positioned over the sump H, the opposite end flange 25 will substantially fit into the offset IT in the end wall l2 of the sump H so as to be supported thereby.

The bottom surface of the inturned flanges 24a may be covered by means of a non-metallic strip of material, such as rubber 26, secured to the flange in any suitable manner and serving the purpose of preventing metalto metal contact when the drainboard is shifted from one sump to the other. In like manner, the bottom inturned flanges 25a of the end flanges 2.5 of the drainboard may be provided with similar non-metallic strips 26, as illustrated. in Fig. 2. A pair'of longitudinally spaced pressed metal brackets 21 are mounted on the underside of the drainboard a suitable distance inwardly of each of the longitudinally extending side flanges 24. Each bracket 21 has a top flange 21a secured, as by spot welding, to the underside of the drainboard and also has a bottom flange 21b resting upon the inturned flange 24a and also secured thereto, as by spot welding. As illustrated in Figs. 4 and 5, the longitudinally spaced brackets 21 at each side of the drainboard carry studs 28 riveted to tapered portions 210 of the brackets so as to extend upwardly at an incline. Journalled on these studs are anti-friction rollers 29 and 29a each projecting in part through an aperture 30 in the flange 24. Each of the four rollers thus mounted at the sides of the drainboard may be formed of rubber or other suitable non-metallic material and are adapted at predetermined times to have rolling engagement with the offset step i I.

When the drainboard is in position over the sump ID, as in Fig. 2, with the end flange 25 seated on the step I! at the end of the sink. the corresponding end of the drainboard will be elevated to the level of the rim l8 thus raising the adjacent rollers 29 off from the step H, as shown in Fig. 4. However, with the notch 3| at the opposite end of the drainboard seated over the partition 20, the rollers 29a adjacent thereto will contact, or substantially so, the seat or ledge IT, as shown in Fig. 5. With the drainboard thus positioned the notches ill will anchor it in position preventing unwanted displacement thereof while in use. The drainboard may, however, be shifted a short distance to the left in Fig. 2, thereby tilting the lefthand end upward with the bottom of the side flanges 24 resting on the partition 20 and at the same time lowering the opposite end of the drainboard to a point Where the rollers 29 rest upon the step 11. In this position the drainboard will slope in the opposite direction from that shown in Fig. 2 and will then drain into the sump H]. In this manner the drainboard may be positioned over the same sump into which it drains.

The drainboard, as seen in the drawings, is narrower than the distance between the side walls i 3 and I 4 of each sump below the offset l1. However, the rollers 29 project laterally a distance sufficient to overlie the step and also extend below the upper edges of the notches 3|. Hence, when either end of the drainboard is withdrawn from the end step, such end of the drainboard will drop down a small distance until the adjacent rollers rest on the step and support it. The rollers, of course, will have rolling engagement on the step so as to facilitate shifting the drainboard from one sump to the other.

It will be understood that when the drainboard is positioned over the sump Ii with the notches 3| at the righthand end thereof seated over the partition 20, the drainboard will be supported in the same manner as in Figs. 1 and 2 excepting the reverse thereof. In such case the rollers 29a will occupy the position shown in Fig. 4 and the rollers 29 will occupy the position shown in Fig. 5, and the drainboard will slope so as to drain water into the sump I0.
